Description

Technical Field

[0001] The utility model relates to the technical field of acoustomagnetic anti-theft, in particular to an acoustomagnetic anti-theft label shell and an acoustomagnetic anti-theft label. Background Art

[0002] Acousto-magnetic anti-theft soft tags are a key anti-theft measure for over-the-counter retail sales. Due to their excellent alarm performance and extremely low false alarm rate, they are widely used in supermarkets, shopping malls, chain stores, and other locations worldwide. These tags are typically affixed to product packaging or placed inside boxes. Items selected by customers are demagnetized at the checkout counter, preventing them from triggering the store's entrance alarm system. If a thief attempts to remove an item from the store, the tag, once within range of the entrance's acoustic-magnetic alarm system, will quickly trigger an alarm, alerting store staff and deterring the thief.

[0003] Currently, the main acoustic magnetic anti-theft labels (plate labels or roll labels) on the market are composed of a multi-layer structure including a PS (polystyrene) / PE plastic composite shell, an amorphous resonant plate, a bias plate, a PE / PET plastic composite sealing cover, and self-adhesive paper. Referring to patent documents such as US4510489, US10339776B2, CN201838126U, and CN 102930683A, existing acoustic magnetic anti-theft labels are made by heat-sealing different plastic composite films. After being discarded with the outer packaging of the product, they are difficult to recycle and cannot be naturally degraded by the environment, causing environmental impact.

[0004] While some degradable acousto-magnetic anti-theft labels exist, such as CN113706810B, which discloses an acousto-magnetic anti-theft label with a shell made of PLA (biodegradable plastic), which requires the label to be naturally degraded in a composting environment after being discarded along with the outer packaging, PLA is expensive and easily degraded during processing, making it difficult to manufacture. This results in high prices for these labels, forcing consumers to pay a high price to replace traditional acousto-magnetic anti-theft labels. CN216161189U, which discloses an acousto-magnetic anti-theft label with a paper shell, discloses a paper material label. However, moisture can affect the shell strength and alarm performance of this type of label, resulting in poor stability. Utility Model Content

Furthermore, the main housing and sealing cover can be easily formed by bending or machining, and the raw materials are relatively inexpensive, thus reducing the cost of the acousto-magnetic anti-theft tag and improving its product competitiveness. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Figure 1 This is an exploded view of the acoustic-magnetic anti-theft tag made of wood or bamboo veneer according to the present invention.

[0032] Figure 2 This is an exploded view of the acoustic-magnetic anti-theft tag made of wood or bamboo board in the utility model.

[0033] Among them: 1-main shell, 2-resonance plate, 3-sealing cover, 4-bias plate, 5-double-sided tape, 6-isolation paper. DETAILED DESCRIPTION

[0034] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0035] like Figure 1-2 As shown, an acoustomagnetic anti-theft tag of a preferred embodiment of the present invention includes a biasing plate 4 and an acoustomagnetic anti-theft tag shell, the acoustomagnetic anti-theft tag shell includes a main shell 1 and a sealing cover 3, the main shell 1 is provided with a resonance plate accommodating cavity, the sealing cover 3 is covered on the main shell 1 and closes the resonance plate accommodating cavity; the main shell 1 and the sealing cover 3 are both made of environmentally friendly materials, preferably wood or bamboo, and the main shell 1 is formed by bending wood veneer, or is machined from wood or bamboo boards.

[0036] The resonant plate accommodating cavity houses several resonant plates 2. A biasing plate 4 is fixedly connected to one surface of the sealing cover 3 and positioned outside the housing of the acoustic-magnetic anti-theft tag. Double-sided tape 5 is also included, one surface of which adheres to the outer surface of the sealing cover 3. The other surface of the tape is covered with release paper 6. When the tape is needed, the release paper 6 is removed and the other side of the tape is applied to the desired object, making operation simple and convenient.

[0037] The acousto-magnetic anti-theft tag based on the above-mentioned technical features utilizes wood or bamboo to form the main housing 1 and sealing cover 3. Once the tag is discarded after use, the wood or bamboo will rapidly degrade in the natural environment, thus minimizing environmental impact. Furthermore, because wood and bamboo are both common and inexpensive materials, and fabrication requires only bending or machining, manufacturing is simple and convenient, reducing the price of the acousto-magnetic anti-theft tag.

[0038] In this embodiment, the material of the sealing cover 3 and the main shell 1 can be the same or different, but preferably the same. The thickness of the sealing cover 3 is 0.1 to 0.25 mm, preferably 0.1 to 0.15 mm, such as 0.11 mm, 0.12 mm, 0.13 mm, 0.14 mm, 0.15 mm, 0.16 mm, 0.17 mm, 0.18 mm, 0.19 mm, 0.2 mm, 0.21 mm, 0.22 mm, 0.23 mm, 0.24 mm, etc., or any value or range between any two values. As for the main shell 1, its thickness is 2 to 3 mm. When veneer is used to make the main shell 1, the thickness of the veneer is 0.3 to 0.35 mm, such as 0.31 mm, 0.32 mm, 0.33 mm, 0.34 mm, etc., or any value or range between any two values ​​mentioned above. When the main shell 1 is made of wooden or bamboo boards, the thickness of the wooden or bamboo boards is 2 to 3 mm, preferably 2.5 to 3 mm, such as 2.6 mm, 2.7 mm, 2.8 mm, 2.9 mm, etc., that is, the installation groove can be directly dug out on the wooden or bamboo boards.

[0039] In this embodiment, the inner bottom of the main housing 1 is provided with reinforcing ribs for supporting the resonant plate 2. The provision of these reinforcing ribs not only improves the strength of the acousto-magnetic anti-theft tag itself, but also reduces the contact area between the inner surface of the main housing 1 and the resonant plate 2, reducing resonance interference and improving alarm performance. The thickness of the reinforcing ribs is determined based on the depth of the resonant plate accommodating cavity and the number and thickness of the resonant plates 2, ensuring that after the resonant plates 2 are installed, the upper surface of the topmost resonant plate 2 is flush with, or slightly lower than, the upper end surface of the resonant plate accommodating cavity. Therefore, the thickness of the reinforcing ribs varies for different products. In most cases, the thickness between the bottom wall of the resonant plate accommodating cavity and the bottom surface of the main housing 1 can be roughly equivalent to the thickness of the sealing cover 3.

[0040] In this embodiment, the sealing cover 3 and the main shell 1 are bonded by water-based glue, which not only ensures the connection strength between the sealing cover 3 and the main shell 1, but also the water-based glue is easy to degrade. When the label is discarded after use, it can be quickly degraded in the natural environment, avoiding impact on the environment.

[0041] At the same time, to ensure the bonding strength and sealing performance of the water-based adhesive, a waterproof modifier and a bonding enhancer can be added to its raw materials. Specifically, the raw materials of the water-based adhesive include, by weight: 80-120 parts of polyurethane, 1-3 parts of hydroxyethyl cellulose, 4-8 parts of polyvinyl alcohol, 0.5-1 part of triethylamine, 8-16 parts of natural latex, 4-6 parts of polymethylphenylsiloxane, 1-3 parts of diethylene glycol monobutyl ether, 4-8 parts of waterproof modifier, 1-4 parts of bonding enhancer, 12-24 parts of deionized water, 1-5 parts of preservative, and 0.5-3 parts of defoaming agent.

[0042] The waterproof modifier uses nano-titanium dioxide, antimony trioxide and magnetized powder as base materials, and is modified with polyurethane together with the bonding enhancer, effectively improving the waterproof performance and connection strength of the water-based glue, thereby ensuring the connection strength and waterproof sealing between the sealing cover 3 and the main shell 1, improving the durability and reliability of the product, and improving user satisfaction.

[0043] In this embodiment, the width of the resonance plate accommodating cavity corresponds to the width of the resonance plate 2, and the width of the resonance plate 2 is 1.6 to 6.5 mm. The number of resonance plates 2 is 1 to 7, and when the number of the plurality of resonance plates is 2 to 7, the plurality of resonance plates are stacked and arranged in the resonance plate accommodating cavity. During the specific production process, it is necessary to consider both the number and width of the resonance plates 2 to select whether to use wood chips, wooden boards, or bamboo boards. Specifically:

[0044] When the width of the resonant sheet 2 is less than 4 mm and the number of the resonant sheets 2 is less than or equal to 4, the main housing 1 is made of bamboo sheets or bamboo boards. This is because when the width of the resonant sheet 2 is less than 4 mm and the number of the resonant sheets 2 is less than or equal to 4, if wood is used, the wood cannot resonate with the resonant sheet 2, so bamboo sheets or bamboo boards are the only option.

[0045] When the width of the resonance piece 2 is greater than or equal to 5.5 mm, or when the number of the resonance pieces 2 is greater than four, the main housing 1 can be made of any one of wood chips, wooden boards, or bamboo boards. When the number of the resonance pieces 2 is sufficient, or the width of the resonance pieces 2 is sufficient, the resonance pieces 2 can resonate with either wood or bamboo, so any one of wood chips, wooden boards, or bamboo boards can be used.

[0046] In addition, the thickness of the resonant plate is 20 to 40 μm. After the number and thickness of the resonant plates are determined, the material used for the main shell 1 is also determined accordingly. At the same time, since the thickness of the main shell 1 is within 2 to 3 mm, a resonant plate accommodating cavity of a corresponding depth is required to accommodate the resonant plate 2. Therefore, the thickness between the bottom surface of the main shell 1 and the bottom wall of the resonant plate accommodating cavity is also relatively determined. To ensure the overall strength of the acousto-magnetic anti-theft tag housing, the thickness of the sealing cover 3 must correspond to the minimum wall thickness of the main shell 1 (i.e., the thickness between the bottom wall of the resonant plate accommodating cavity and the bottom surface of the main shell 1). Since the minimum wall thickness of the main shell 1 is related to the depth of the resonant plate accommodating cavity, and its depth is related to the number of resonant plates 2, the thickness of the sealing cover 3 is interrelated with the main shell 1 and the number of resonant plates 2. Specifically:

[0047] Assuming the number of the resonance pieces 2 is n, the thickness of the resonance piece 2 is t, the thickness of the main housing 1 is H1, and the thickness of the sealing cover 3 is H2, then the following conditions are satisfied:

[0048] When the main shell 1 and the sealing cover 3 are made of the same material, H2 = (0.05-0.25)(H1-10nt);

[0049] When the main housing 1 is made of bamboo and the sealing cover 3 is made of wood, H2 = (0.1-0.25)(H1-10nt);

[0050] When the main housing 1 is made of wood and the sealing cover 3 is made of bamboo, H2 = (0.05-0.2)(H1-10nt);

[0051] At the same time, the above three cases all meet the following conditions: when n≤4, H2≤0.2mm; when n≥5, H2≥0.15mm.

[0052] From the above, it can be seen that when making the shell of the acousto-magnetic anti-theft tag, the main shell 1 is first made of the corresponding material according to the width of the resonance piece 2, and the thickness of the main shell 1 is ensured; then, according to the thickness of the sealing cover 3 being 0.1 to 0.25 mm, and according to the number and thickness of the resonance pieces 2, according to the above relationship, the material used to make the sealing cover 3 is selected and it satisfies the above relationship.

[0053] It can be seen that the number and width of the resonance plates 2, the material and thickness of the main shell 1, and the material and thickness of the sealing cover 3 are interrelated and influence each other. All factors should be fully considered during production to ensure that each factor meets the above requirements.

[0054] In addition, it should be noted that if veneer is directly used to make the main shell 1, the thickness of the veneer can be the thickness between the bottom wall of the resonance plate accommodating cavity and the bottom surface of the main shell 1. At this time, the thickness between the bottom wall of the resonance plate accommodating cavity and the bottom surface of the main shell 1 may not be equivalent to the thickness of the sealing cover 3. The thickness of the sealing cover 3 is directly determined by the relationship between H2 and H1 mentioned above.

[0055] In this embodiment, wood or bamboo boards are used. In actual production, if the four corners of the resonance plate cavity are right angles, machining may cause the wood or bamboo to crack or break. Therefore, arcs are provided at the four corners of the resonance plate cavity to prevent cracking or breaking of the wood or bamboo. If the diameter of the arc is D, D can be slightly less than half the width of the resonance plate cavity.

[0056] In summary, the acoustic magnetic anti-theft tag of the present invention has a tag shell made of natural, environmentally friendly materials such as wood or bamboo. Wood or bamboo has better antistatic properties and mechanical rigidity than plastic, thereby improving the performance of the tag. The surface processing characteristics of wood or bamboo are utilized to add reinforcing ribs, thereby improving the strength of the tag and reducing the contact area between the inner surface of the tag shell and the resonance plate 2, thereby reducing resonance interference and improving the alarm performance. After the tag is discarded after use, the wood and bamboo can be degraded in the natural environment, thus achieving true environmental protection requirements. The tag has a natural color and is beautiful and elegant, making it suitable for the anti-theft protection needs of handicrafts, gifts, and other commodities.

[0057] In order to solve the above technical problems, the present invention also provides a method for manufacturing an acoustic-magnetic anti-theft tag, which includes two situations:

[0058] 1. When the main housing 1 is made of wood veneer, the manufacturing method includes the following steps:

[0059] Select wood skin with a thickness of 0.3mm-0.35mm and make it into rolls to facilitate continuous production;

[0060] The rolled wood bark is humidified and steam-heated to soften it. The humidification temperature is room temperature, preferably 20-25°C. The humidification time depends on the dryness of the veneer, generally 1-10 seconds, ensuring a humidity of 40%-60% RH. The steam temperature is 70-95°C. After humidification and heating, the veneer becomes soft and easier to bend.

[0061] The softened wood sheet is cut and bent to prepare a main housing 1 having a cavity for accommodating the resonance plate;

[0062] Apply glue on the top edge surface of the main shell 1, and the glue is preferably water-based glue;

[0063] Place a plurality of resonance sheets 2 into the resonance sheet accommodating cavity of the main housing 1;

[0064] Select wood or bamboo veneer with a thickness of 0.1mm-0.25mm, and make the sealing cover 3 according to the shape of the upper end surface of the main shell 1. The material of the sealing cover 3 is preferably the same as that of the main shell 1;

[0065] Adhere the sealing cover 3 to the main housing 1 to seal the resonance plate accommodating cavity;

[0066] The biasing sheet 4 is fixed to the surface of the sealing cover 3 with double-sided tape, and a release paper is attached to the double-sided tape. The double-sided tape 5 is a double-sided tape made of water-based acrylic adhesive.

[0067] 2. When the main housing 1 is made of wood or bamboo, the manufacturing method includes the following steps:

[0068] A main housing 1 having a cavity for accommodating the resonance plate is prepared by machining a wood or bamboo board with a thickness of 2 to 3 mm;

[0069] Apply glue on the top edge surface of the main shell 1, and the glue is preferably water-based glue;

[0070] Place a plurality of resonance sheets 2 into the resonance sheet accommodating cavity of the main housing 1;

[0071] Select wood or bamboo veneer with a thickness of 0.1 to 0.25 mm, and make a sealing cover 3 according to the shape of the upper end surface of the main shell 1. The material of the sealing cover 3 is preferably the same as that of the main shell 1;

[0072] Adhere the sealing cover 3 to the main housing 1 to seal the resonance plate accommodating cavity;

[0073] The biasing sheet 4 is fixed to the surface of the sealing cover 3 with double-sided tape, and release paper is attached to the double-sided tape 5 .

[0074] In addition, for the above two situations, after the acousto-magnetic anti-theft tag is manufactured, its performance needs to be tested. The testing method is as follows:

[0075] In a single-door Ultra-post system, the alarm distances of the acoustic-magnetic anti-theft tag in the X, Y, and Z directions are measured and defined as X1, Y1, and Z1 respectively;

[0076] Define the alarm distances of the plastic shell acoustic magnetic anti-theft tag as X2, Y2, and Z2 respectively;

[0077] Comparing the above alarm distance with the alarm distance of the plastic shell acousto-magnetic anti-theft tag, we can obtain X1-X2=X0, Y1-Y2=Y0, Z1-Z2=Z0;

[0078] Compare X0, Y0, and Z0 with the threshold S respectively. If X0, Y0, and Z0 are all within the threshold, the result is qualified. If any one of them is not within the threshold, the result is unqualified. The value range of the threshold S is different in different directions. Specifically:

[0079] Corresponding to the X direction of the acousto-magnetic anti-theft tag, that is, corresponding to X0, the threshold is S1, and the value range of S1 is ±10cm, such as ±5cm, ±6cm, ±7cm, ±8cm, ±9cm, etc.;

[0080] Corresponding to the Y direction of the acousto-magnetic anti-theft tag, that is, corresponding to Y0, the threshold is S2, and the value range of S2 is ±5cm, such as ±2cm, ±3cm, ±4cm, etc.;

[0081] Corresponding to the Z direction of the acousto-magnetic anti-theft tag, that is, corresponding to Z0, the threshold is S3, and the value range of S3 is ±7 cm, such as ±3 cm, ±4 cm, ±5 cm, ±6 cm, etc.

[0082] To illustrate the technical effects of this application, specific examples are listed below to prove:

[0083] Example 1

[0084] Wood veneer with a thickness of approximately 0.3 to 0.35 mm is selected and rolled into rolls to facilitate continuous production. The rolled wood veneer is humidified, steam-heated, and then bent to form the outer shell of the acoustic magnetic anti-theft soft tag with a resonant plate cavity structure. Water-based glue is applied to the top of the main shell 1 and is ready for use.

[0085] Place three 6mm resonance sheets 2 into the resonance sheet accommodating cavity of the manufactured acoustic magnetic anti-theft label shell in the morning, then make a sealing cover 3 with a specification of 80g and a thickness of 0.1mm to 0.15mm of wood veneer, stick the main shell 1 and the sealing cover 3 together, fix the bias sheet 4 on the surface of the sealing cover 3 with a double-sided tape 5 of water-based acrylic adhesive, and then cover it with double-sided tape 5 and isolation paper 6 to make the label of this utility model ( Figure 1 The performance of this tag was compared with that of a plastic-encased tag with the same resonant and offset plates. In a single-door Ultra-post system, the alarm distances in the X, Y, and Z directions were 80-90cm, 30-40cm, and 40-60cm, respectively. These distances are essentially the same as those of three 6mm tags in PS / PE and PE / PET sealed enclosures.

[0086] The above values ​​are verified by H2=(0.05~0.25)(H1-10nt); and when n≤4, H2≤0.2mm, which satisfies the above relationship.

[0087] Example 2

[0088] Bamboo bark with a thickness of approximately 0.25mm to 0.3mm was rolled into rolls to facilitate continuous production. The rolled bamboo bark was humidified, steam-heated, and then bent to form the outer shell of the acoustic-magnetic anti-theft soft tag, which has a cavity structure that accommodates the resonant plate. However, the relatively high hardness and brittleness of the rolled bamboo bark made it unsuccessful, and this method failed.

[0089] Example 3

[0090] Wood veneer with a thickness of approximately 0.25mm to 0.3mm is used and rolled into rolls to facilitate continuous production. The rolled wood veneer is humidified, steam-heated, and then subjected to a hot molding process. This process easily cracks and makes it impossible to form a housing with a resonant plate cavity.

[0091] Example 4

[0092] Bamboo skin with a thickness of approximately 0.25mm to 0.3mm is used and rolled into rolls to facilitate continuous production. However, the rolled bamboo skin is humidified, steam-heated, and then subjected to a hot-molding process. This easily cracks and cannot be used to form a housing with a resonant plate cavity structure.

[0093] Example 5

[0094] A wooden board with a thickness of about 3 mm was selected. After humidification, steam heating, and then hot molding, the wooden board was prone to cracking and could not be made into a shell that met the requirements. This method failed.

[0095] Example 6

[0096] A bamboo board with a thickness of about 3.5 mm was selected. After being humidified, steam-heated, and then subjected to a hot molding process, the bamboo board was prone to cracking and could not be made into a shell that met the requirements. This method failed.

[0097] Example 7

[0098] A wooden board with a thickness of about 2.5mm to 3mm is selected and machined to form the shell of the acoustic magnetic anti-theft soft tag with a resonance plate accommodating cavity structure, and water-based glue is applied on the top of the main shell 1 for use.

[0099] Place three 6mm resonance sheets into the resonance sheet accommodating cavity of the manufactured acoustic magnetic anti-theft label shell, make a sealing cover 3 with a 0.15mm to 0.2mm thick veneer, stick the main shell 1 and the sealing cover 3 together, fix the bias sheet 4 on the surface of the sealing cover 3 with double-sided tape 5, and then cover it with double-sided tape and isolation paper 6 to make the label of this utility model ( Figure 2A performance comparison of this tag with plastic-encased tags using the same resonant and offset plates revealed that, in a single-door Ultra-post system, the alarm distances in the X, Y, and Z directions were 82-92cm, 32-42cm, and 42-62cm, respectively. These distances are essentially the same as, or slightly better than, those of three 6mm tags in PS / PE and PE / PET sealed enclosures.

[0100] The above values ​​are verified by H2=(0.05~0.25)(H1-10nt); and when n≤4, H2≤0.2mm, which satisfies the above relationship.

[0101] Example 8

[0102] A bamboo board with a thickness of about 2.5mm to 3mm is selected and machined to form the shell of the acoustic magnetic anti-theft soft tag with a resonance plate accommodating cavity structure, and water-based glue is applied on the top of the main shell 1 for use.

[0103] Place three 6mm resonance sheets 2 into the resonance sheet accommodating cavity of the manufactured acoustic magnetic anti-theft label shell, make a sealing cover 3 with bamboo skin with a thickness of 0.15mm to 0.2mm, stick the main shell 1 and the sealing cover 3 together, fix the biasing sheet 4 on the surface of the sealing cover 3 with double-sided tape 5, and then cover it with double-sided tape 5 and isolation paper 6 to make the label of this utility model ( Figure 2 A performance comparison of this tag with plastic-encased tags using the same resonant and offset plates revealed that, in a single-door Ultra-post system, the alarm distances in the X, Y, and Z directions were 82-92cm, 32-42cm, and 42-62cm, respectively. These distances are essentially the same as, or slightly better than, those of three 6mm tags in PS / PE and PE / PET sealed enclosures.

[0104] The above values ​​are verified by H2=(0.05~0.25)(H1-10nt); and when n≤4, H2≤0.2mm, which satisfies the above relationship.

[0105] Embodiment 9

[0106] Wood veneer with a thickness of approximately 0.3mm-0.35mm is selected and rolled into rolls to facilitate continuous production. The rolled wood veneer is humidified, steam-heated, and then bent to form the outer shell of the acoustic magnetic anti-theft soft tag with a resonant plate accommodating cavity structure. Water-based glue is applied to the top of the main shell 1 and is ready for use.

[0107] Four 4.2mm resonant sheets 2 were placed into the resonant sheet cavity of a prefabricated acousto-magnetic anti-theft tag housing. A sealing cover 3 was then made from 80g of 0.1mm-0.15mm thick wood veneer. The main housing 1 and sealing cover 3 were then bonded together. A biasing sheet 4 was affixed to the surface of the sealing cover 3 using double-sided tape 5 made of water-based acrylic adhesive.

[0139] The above embodiments demonstrate that the main housing can be made from either wood or bamboo boards through machining, and from wood sheets through bending, but not from bamboo sheets. Specifically, when the width of the resonant sheet is less than 4 mm and the number of resonant sheets is less than or equal to four, the main housing is made from bamboo sheets or bamboo boards. When the width of the resonant sheet is greater than or equal to 5.5 mm, the main housing can be made from any of wood sheets, wood sheets, or bamboo boards. When the number of resonant sheets is greater than four, the main housing can be made from any of wood sheets, wood sheets, or bamboo boards. Both wood sheets and bamboo sheets can be used to make the sealing cover.

[0140] At the same time, it can be seen from the above embodiments that wood and bamboo can be used to make acoustic magnetic anti-theft labels with similar or better alarm performance than plastic shell labels. Wood and bamboo are both renewable materials and can be recycled to obtain raw materials for the production of acoustic magnetic anti-theft labels. Moreover, wood labels and bamboo labels can be naturally degraded after use and disposal, making them ideal green and environmentally friendly labels.

[0141] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
